Aluminum Corona Shielding Spheres Design For 460kV Terminal Bushing

Aluminum corona shielding sphere is also known as corona shielding ball and used for 460kV terminal bushing on power transformer, which are mainly made of aluminum alloy.

Generally the aluminum corona shielding sphere and corona ring need to be polished bright to achieve more smooth and no burr surface finish to ensure better corona shielding effect.

Corona shielding spheres are suitable for the voltage form of alternating current (AC), which can distribute the high voltage evenly around the object to ensure that there is no potential difference (PD) between the various parts of the spheres.

When design aluminum corona shielding spheres with Chinese manufacturers, if you are worried about the results of products design. If yes, here is the right place you come to visit.

Without further ado, let’s jump straight into the topic to find the right solutions on aluminum corona shielding spheres and balls design for 460kV terminal bushings.

If client’s inquiry aluminum corona shielding sphere has same diameter and size, all is going well.

There is no need more time to design and develop new mould. If the corona shielding sphere outer diameter is customized or it has no same mould in stock.

Then the new mould of aluminum corona shielding spheres will be designed and developed.

If the mould is our stock standard, the mould is free of charge. If it is customized one, the extra design drawing and fee will be needed.

The mould of aluminum corona shielding sphere refers to the tooling used to produce sphere in molding.

Choosing The Right Raw Materials For Aluminum Corona Shielding Sphere Design


Aluminum alloy, it is a popular raw material to use for aluminum corona shielding spheres and corona rings production.

It depends on aluminum corona shielding sphere design and applications.

The customized outer diameter aluminum corona shielding spheres are usually made from 6061 or 6063 aluminum alloy that is formed and welded.

Aluminum Corona Shielding Sphere Wall Thickness Design


Here we should discuss the sheet metal and welding type aluminum corona shielding sphere wall thickness.

Wall thickness of bending and welding plate will be from 2.0mm to 20mm.

Usually the 2.5mm thickness plate is for 500mm outer diameter corona shielding sphere production and design.

The larger thickness sphere will have high strength.

In a word, the thickness of plate of corona shielding sphere will be designed and discussed with customers together.

Aluminum Corona Shielding Sphere Outer Diameter Design


Outer diameter of aluminum corona shielding sphere depends on high voltage grade on terminal bushings.

As the high voltage level of terminal bushing becomes higher, the diameter of the corresponding aluminum corona shielding sphere must be enlarged.

Here we should introduce our design and processing capabilities of the large outer diameter of these spheres and balls.

The biggest diameter dimension of one sphere is up to 6000mm.

During the aluminum corona shielding ball production process, our team will check the sizes frequently and input our Just-in-Time record.

This could ensure all aluminum corona shielding spheres are within the good manufacturing quality.
